IMPROVEMENT IN CUTTING APPARATUS FOR HARVESTERS.

Specification forming part of Letters Patent No. 128,456, dated July 2,1872.

SPECIFICATION.

To all whom it may concern:

Be it known'that I, SYLvEsTEE W. BEACH, of Ypsilanti, in the county ofWashtenaw and State of Michigan', have invented certain new and usefulImprovements in Beaping-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters ofreferencemarked thereon which form a part of this specification. s

My invention relates to that class of cutterbars for reapers and mowersin which there are two reciprocating cutters operating in oppositedirections; and it consists in the arrangement of the devices wherebythe cutters are made to operate in opposite directions, as will behereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertaius to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichis represented a plan view of my cutter-bar.

A represents the finger-bar with the fingers B B. C and D are the twocutter-bars, operating on the finger-bar A through the n gers B B, allbeing constructed in any of the known and usual ways. The cutter-bar Cis, at its inner end, provided with an extension or bar, C', rigidlyattached to it, and extending at right angles with it toward the rear.To this extension C is pivoted the pitman E, which gives motion to saidcutter-bar C, and'ispperated by any suitable mechanism on the body ofthe reaper or mower. On the inner end of the linger-bar is placed alever, G, which is pivoted through its center, and both ends areslotted, as shown. From the rear end of the extension C a pin, a,extends downward into the slot at one end of the lever Gr, while asimilar pin, b, extends downward, from the inner end ofthe cutter-bar D,into the other end of the said lever.

Thus it will be seen that as the cutter-bar C is, by the machinery onthe body of the reaper or mower, operated back and forth, the othercutter-bar D is, by the pins a b and the slotted centrally-pivoted leverG, also operated back and forth, but always in the opposite directionfrom that of the former.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In combination with the reciprocating cutter-bars C D the extension barC', pitman E, centrally-pivoted lever G having slotted ends, and thepins a b, all constructed and arranged substantially as and for thepurposes herein set forth.

In testimony that I claim the foregoing as my own I afx my signature npresence of two witnesses.
